The sophomore class sells tickets to a benefit concert to raise money. Each ticket sells for $15. How much money do they raise?
A. m=15+t
B. m=t/15
C. t=15m
D. m=15t
Answer:
D.m=15t
Step-by-step explanation:
If the number of tickets is t and the total amount of money collected is m then a product of the price per ticket with the cost of the ticket gives the amount of money collected from the sale of the tickets.
therefore m= t×15
m=15t
Answer:
D. m = 15t
Step-by-step explanation:
We have to assume that m is supposed to stand for the money (in dollars) that results from the sale of t tickets. Then the sale of t=1 ticket will result in m=15 dollars. Only one of the offered formulas will give this result:
m = 15t
_____
Comment on the problem
Variables need to be defined. We'd prefer to see some discussion of how concert expenses are covered, so we can be assured that ticket sales directly relate to money raised.
Identify the area of the rhombus.
Answer:
[tex]A=240\ m^{2}[/tex]
Step-by-step explanation:
we know that
A rhombus is a parallelogram with four congruent sides, the diagonals are perpendicular bisectors of each other
The area of a rhombus is equal to
[tex]A=\frac{1}{2}(D1*D2)[/tex]
where
D1 and D2 are the diagonals
In this problem we have
[tex]D1=16\ m[/tex]
Applying the Pythagoras Theorem find D2
[tex]17^{2} =(D2/2)^{2}+(16/2)^{2}[/tex]
[tex](D2/2)^{2}=17^{2}-(16/2)^{2}[/tex]
[tex](D2/2)^{2}=225[/tex]
[tex](D2/2)=15[/tex]
[tex]D2=30\ m[/tex]
Find the area of the rhombus
[tex]A=\frac{1}{2}(16*30)=240\ m^{2}[/tex]

Credit cards can only lead to debt that is difficult to eliminate and should be avoided at all costs. Please select the best answer from the choices provided T F
This statement is false.
Step-by-step explanation:
Credit cards can only lead to debt that is difficult to eliminate and should be avoided at all costs. This is false.
This is not a standard statement that credit cards always lead to debt. A person should use his credit card with responsibility. He should pay the bills timely to avoid accumulation of debt and other fines. Only when a person uses his card irresponsibly and does not pay dues timely, can lead to debts.
So, this is a false statements.

Answer:
See below.
Step-by-step explanation:
1. (1 / 2)[cos(a – b) – cos(a + b)]
= 1/2 ( cosa cosb + sina sinb - (cosa cosb - sina sinb)
= 1/2 ( cosa cosb - cosa cos b + sina sinb + sina sinb)
= 1/2 ( 2 sina sinb)
= sina sinb.
(I used the 2 identities cos(a - b) = cosa cosb + sina sinb) and
cos (a + b) = cosa cosb - sina sinb.)
2. sin (π/2 - x) = sin (π/2) cos x - cos(π/2) sin x
= 1 * cos x - 0 * sinx
= cosx - 0
= cos x.
(I used the identity sin(a - b) = sina cosb - cosa sinb
and the fact that sin(π/2) = 1 and cos (π/2) = 0. )
Answer:
1. sin a sin b = (1 / 2)[cos(a – b) – cos(a + b)]
Calculation:
Taking L.H.S. of above equation
(1 / 2)[cos(a – b) – cos(a + b)]
= (1 / 2) [ (cos a cos b + sin a sin b) - (cos a cos b - sin a sin b)]
{∵ cos(a – b) = cos a cos b + sin a sin b & cos(a + b) = cos a cos b - sin a sin b}
= (1 / 2) [ cos a cos b + sin a sin b - cos a cos b + sin a sin b]
= (1 / 2) [2 sin a sin b]
= sin a sin b
2. sin((π / 2) – x) = cos x
Calculation:
sin((π / 2) – x) = sin (π / 2) cos x - cos (π / 2) sin x
{∵sin(a - b) = sin a cos b - cos b sin a
& sin (π / 2) = 1 & cos (π / 2) = 0}
= 1 × cos x - 0 × sin x
= cos x
The interest rate r required to increase your investment p to the amount a in t years is found by [tex]r=(\frac{a}{p} )^\frac{1}{t} -1[/tex]. Find the interest rate r for p = 2700, a = 6400, and t = 3. Round to the nearest hundredth.
The interest rate required to increase an investment of $2700 to $6400 in 3 years, using the formula r=(a/p)^(1/t) - 1, is approximately 38.5% per year when compounded annually.
Explanation:The subject at hand deals with the concept of finding the interest rate on an investment. The provided equation, which represents the interest rate formula, is: r=(a/p)^(1/t) - 1. Here, the variables represent the following: r is the interest rate, a is the amount of money accumulated after t years (the future value of the investment), p is the principle/original amount (the initial value of the investment), and t is the time in years. By inserting the given values (p = 2700, a = 6400, t = 3) into the formula, we get: r = (6400 / 2700)^(1 / 3) - 1.
The next step is to calculate the arithmetic for the values inside the parenthesis first, then raise it to the power of 1/3 (which is the cube root), and finally subtract 1 from the result. Doing these calculations you obtain approximately 0.385, or 38.5% when expressed as a percentage. So, the interest rate that is required to increase your investment of $2700 to $6400 in 3 years is approximately 38.5% per year when compounded annually.

A duplex generates $1,400 rent for each of its two units per month. The property has been recently appraised for $350,000. What is this property's GIM? 4.8, 9.6, 10.4, or 20.83??
Answer:
10.4
Step-by-step explanation:
To get the property's gross income multiplier (GIM), you divide its appraised value by its gross annual rental income.
Rental income = 2 × $1400/1 month × (12 months/1 yr)
= $33 600/yr
GIM = $350 000/$33 600 = 10.4
The property's GIM is 10.4.

How many sums????????????????? EXPLAIN!
Answer: 7
Step-by-step explanation:
The 1st spinner can land on 2, 3, 4, or 5
The 2nd spinner can land on 2 or 3
The 3rd spinner can land on 6, 7, or 8
1st spinner + 2nd spinner + 3rd spinner:
2 + 2 + 6 = 10, 2 + 2 + 7 = 11, 2 + 2 + 8 = 12 --> 3 different sums
2 + 3 + 6 = 11, 2 + 3 + 7 = 12, 2 + 3 + 8 = 13 --> 1 different sum
This pattern follows where the only new sums are as follows:
3 + 3 + 8 = 14
4 + 3 + 8 = 15
5 + 3 + 8 = 16
This makes a total of 7 different sums.
You want to save ₹1,17,000 to buy your first self-driving magic carpet. You deposit ₹90,000 in a bank at an interest rate of 6 % 6%6, percent per annum. How many years do you have to wait before you can buy your magic carpet?
Answer:
4.50 yr
Step-by-step explanation:
I assume that this is compound interest.
The compound interest equation is
[tex]A = P(1+ \frac{r }{ n})^{nt}[/tex]
You don't give the frequency of compounding, so I assume that it is once per year.
Data:
A = ₹117 000
P = ₹90 000
r = 6 % = 0.06
n = 1
Calculations:
[tex]117 000 = 90 000(1+ \frac{0.06 }{ 1})^{1 \times t}[/tex]
[tex]117 000 = 90 000(1+ 0.06)^{t}[/tex]
Divide each side by 90 0000
[tex]1.3 = 1.06^{t}[/tex]
Take the logarithm of each side
log1.3 = tlog1.06
0.1139 = 0.025 31t
Divide each side by 0.025 31
t = 4.50 yr
You can buy your magic carpet in 4.50 yr.
Answer: is 5
all you have to do is \(^o^)/
(1,17,000−90,000)=27,000

The scores on a standardized test are normally distributed with a mean of 500 and a standard deviation of 60. Jake scored 520 on the test. Find the percent of students that scored below Jake. Round your answer to the nearest whole number. (Include a step by step description of the process you used to find that percentage.)
*You will need to find the z-score using the z-score formula, the probability using the table, then change the probability to a percent.
Subtract the mean from Jake's score:
520 - 500 = 20
No divide that by the standard deviation:
20/60 = 0.33
This means Jake scored 0.33 standard deviations above the mean.
Now using the Z-table find 0.33: 0.33 = 0.6293 = 62.93% of students scored below Jake.
Rounded to nearest whole number = 63%
Answer:
63% of students
Step-by-step explanation:
Z = (X - μ) / σ
Z = 520 - 500 / 60
Z = 0.33
ON THE Z-TABLE
0.33 = 0.6293
62.93% = 63% of students answer

Given sin theta= 6/11 and sec theta < 0, find cos theta and tan theta.
Answer: option a.
Step-by-step explanation:
By definition, we know that:
[tex]cos^2(\theta)=1-sen^2(\theta)\\\\tan(\theta)=\frac{sin(\theta)}{cos(\theta)}[/tex]
Substitute [tex]sin(\theta)=\frac{6}{11}[/tex] into the first equation, solve for the cosine and simplify. Then, you obtain:
[tex]cos(\theta)=\±\sqrt{1-(\frac{6}{11})^2}\\\\cos(\theta)=\±\sqrt{\frac{85}{121}}\\\\ cos(\theta)=\±\frac{\sqrt{85}}{11}[/tex]
As [tex]sec\theta<0[/tex] then [tex]cos\theta<0[/tex]:
[tex]cos(\theta)=-\frac{\sqrt{85}}{11}[/tex]
Now we can find [tex]tan\theta[/tex]:
[tex]tan\theta=\frac{\frac{6}{11}}{-\frac{\sqrt{85}}{11}}\\\\tan\theta=-\frac{6\sqrt{85}}{85}[/tex]

Two different types of polishing solutions are being evaluated for possible use in a tumble-polish operation for manufacturing intraocular lenses used in the human eye following cataract surgery. 300 lenses were tumble-polished using the first polishing solution, and of this number, 249 had no polishing-induced defects. Another 300 lenses were tumble-polished using the second polishing solution, and 196 lenses were satisfactory upon completion. Is there any reason to believe that the two polishing solutions differ? Use α = 0.01. What is the P-value for this test? There significant difference in the proportion of polishing-induced defects produced by the two polishing solutions at the 0.01 level of significance. The P-value is . Round your answer to three decimal places (e.g. 98.765).
Final answer:
To determine if there is a significant difference between two polishing solutions, a two-proportion z-test can be used, comparing the proportions of polishing-induced defects. If the p-value is less than the significance level (0.01), the null hypothesis is rejected.
Explanation:
To determine if there is a significant difference between the two polishing solutions used in tumble-polishing intraocular lenses, we can perform a hypothesis test. The null hypothesis (H0) is that there is no difference between the proportions of polishing-induced defects for the two solutions, while the alternative hypothesis (Ha) is that there is a difference.
We can use a two-proportion z-test to compare the proportions of defects. The z-test statistic is calculated as:
z = (p1 - p2) / [tex]\sqrt{(p1q1/n1)[/tex] + (p2q2/n2))
where p1 and p2 are the proportions of defects, q1 and q2 are 1-p1 and 1-p2 respectively, and n1 and n2 are the number of lenses polished with each solution. The p-value for this test can be calculated using a standard normal distribution table or a statistical software.
If the p-value is less than the significance level α (0.01 in this case), we reject the null hypothesis and conclude that there is a significant difference between the two polishing solutions.
The p-value for this test cannot be determined without the actual values of p1, p2, q1, q2, n1, and n2.

A car travels at an average speed of 48 miles per hour. How long does it take to travel 180 miles?
Answer:
3 hours and 45 minutes
Step-by-step explanation:
The time to travel 180 miles at an average speed of 48 miles per hour is approximately 3.75 hours. This was calculated using the formula Time = Distance / Speed.
Explanation:The question is based on time, speed, and distance, all correlating with each other, and to solve, we will use the following frequently used formula:
Time = Distance / Speed
We can substitute the given values into our formula. We know our distance is 180 miles and our speed is 48 miles per hour. So, our equation becomes:
Time = 180 miles / 48 miles per hour
After calculating this equation, we get approximately 3.75 hours.
So, it would take approximately 3.75 hours to travel 180 miles at an average speed of 48 miles per hour.
